Troubleshooting & FAQ
Click any question to see the answer
Extension not appearing after installation?
Make sure Developer Mode is enabled and you selected the correct folder (the one containing manifest.json). Try refreshing your extensions page or restarting your browser.
Can't see my transactions?
Ensure you're connected to the correct network (mainnet/testnet) in settings. Your wallet needs to sync with the blockchain, which may take a few moments.
Lost access to my wallet?
You can recover your wallet using your 24-word seed phrase. Click "Import Wallet" and enter your seed phrase. Your funds are always recoverable as long as you have your seed phrase.
How do I switch between mainnet and testnet?
Go to Settings → Network and select your preferred network. This is useful for testing before deploying to mainnet.
Transactions failing or stuck?
Check that you have sufficient ZEC for both the transaction amount and network fees. If stuck, the transaction may need more time to confirm on the blockchain.
Can I use Zync Wallet on mobile?
Currently Zync Wallet is available as a browser extension for desktop Chromium-based browsers only. Mobile support may come in future updates.
Where are my inscriptions shown?
NFTs and ZRC-20 tokens appear in the "Inscriptions" tab. Make sure you're connected to the correct network and your inscriptions have been indexed.
How do I backup my wallet?
Write down your 24-word seed phrase and store it in a secure offline location. Never store it digitally or share it with anyone. This is the only way to recover your wallet.
